Periodic Safety Reviews (PSRs)

Under condition 15 attached to the nuclear site licence, Periodic Safety Reviews (PSRs) must be carried out by the licensee of a nuclear power plant. The reviews are complementary to the day-to-day regulatory controls which are applied to nuclear power stations. They provide the opportunity to undertake a comprehensive study of plant safety, taking into account aspects such as its operational history, ageing factors which could lead to deterioration in safety, and the advances in safety standards since the time of construction or the previous review. From this, the safety of future operation of the plant can be evaluated.
